Disclosed is an intercept system for integrating the personalized services of switchboard attendants associated with on-premises PBX switching systems, with the capabilities of the intercept system for allowing calling parties the opportunity to complete their own calls to the on-premise switching systems when the telephone extension numbers of the called parties are known to the calling parties. Depending on the mode of system operation selected, the intercept system either presents all incoming calls directly to the switchboard attendants, or intercepts all incoming calls and presents the caller the opportunity to complete the call, or a combination in which incoming calls are first offered to the switchboard attendants for assistance and then after a time wherein attendant assistance is not gained, the call is intercepted and the caller is given an opportunity to complete the call. When a call is intercepted a bidirectional communication path is established between the caller and the intercept system wherein a digital announcement circuit transmits an instructional message to the caller soliciting the dialing of the desired on-premise switching system telephone extension number, and a DTMF receiver collects the dialed extension number digits. The digits are then outpulsed to the on-premises switching system and the call to the desired party is completed without the intervention of a switchboard attendant.

Call processing apparatus for queuing calling parties waiting to be connected to a service position, and for calculating queue position data or wait time data and transmitting the queue data to the calling parties. The queued calling parties can also reach alternate destinations by inputting digit information for routing queued calling parties to such destinations.

Call processor for facilitating call completions

Apparatus for recognizing a telephone call supervision signal by comparing its frequency and cadence to the frequency and cadence of a previously learned call supervision signal is provided as part of call completion equipment (10). Call progress tone detector (50) receives a call supervision signal and responds by outputting frequency parametric signals which indicate whether predetermined standard frequencies are present in the received signal. Microprocessor (74) determines the cadence of the received call supervision signal and outputs a corresonding cadence parametric signal. If it is beneficial to learn the received call supervision signal, the frequency and cadence parameters are stored in memory (78). Recognition circuits can then recognize a subsequent telephone call supervision signal by comparing its frequency and cadence parameters to the frequency and cadence parameters stored in memory (78) for at least one learned signal.

Busy/no-answer call completion equipment

A call processor (32) for intercepting incoming calls to a key telephone system (10) and returning a message to a calling party. A digital message storage unit (48) stores messages associating called parties with respective pseudo-telephone numbers so the calling party can input information identifying a desired called party. A CPU (50) of the call processor (32) references a look-up table (52) with the pseudo-telephone number input by the calling party to select and transmit a message via an intercom line (36) to the key telephone system (10). The message carried by the intercom line (36) broadcasts a message relating to the identity of the called party as well as the line to utilize.

A digital message storage unit (48) stores messages associating called parties with respective pseudo-telephone numbers so the calling party can input information identifying a desired called party. A CPU (50) of the call processor (32) references a look-up table (52) with hte pseudo-telephone number input by the calling party to select and transmit a message via an intercom line (36) to the key telephone system (10). The message carried by the intercom line (36) broadcasts a message relating to the identity of the called party as well as the line to utilize.

Call completion equipment (10) is disclosed for use with a switching system (14) for assisting callers to complete telephone calls thereto. If a primary destination telephone set (16) is busy or does not answer, a message is transmitted from a message storage unit (54) to the calling party. The message relates to the selection by the caller of secondary destinations including a switchboard attendent 18, an alternate destination telephone set, a camp-on option or voice messaging facilities. A processor complex (72) processes the digits dialed by the caller in response to the message, using various look-up tables (85-87), and transfers corresponding information to the switching system (14). The switching system (14) completes the call to the secondary destination according to the information. The invention (10) provides automatic camp-on features (87) with regard to predefined telephone sets of the switching system (14). Self-adaptive tone learn apparatus (50) and programs (88) are provided to learn the particular signature characteristics of call progress tones transmitted by the telephone switching system (14).

PBX Intercept and caller interactive attendant bypass system

An improvement is disclosed for telecommunication PCM time division multiplex switching systems of the type having voice access ports, each with a voice path and a signalling path, and having PCM signalling and voice transmit buses to carry information to a switching network. From the network, PCM voice receive buses carry switched voice information to be demultiplexed, converted to analog form and connected to the voice port. A signalling bus carries information from the switching network to registers. The system is improved to enable it to switch data as well as voice information. A data port is provided to accompany each voice port, and the improved system includes means for multiplexing input data at the port and inserting it on the signalling transmit bus once the signalling portion of a call is completed. A receive data bus connects the signalling receive bus to means for demultiplexing data and presenting it to receive data ports. In a system where signalling and voice bits are synchronized on the transmit buses and the bits are switched together at a common location in switching network memory, the voice and data bits are likewise switched together to a common destination.

Integrated voice and data telecommunication switching system

A serial data interface circuit for converting serial digital information having one transmission rate into corresponding digital information of another transmission rate. Such an interface circuit provides a serial data receive section clocked at an incoming data rate and a serial data transmit section clocked at a desired transmission rate. Interposed between the sections is buffer means for asynchronously transferring data information from the receive section to the transmit section whereby a different receive and transmit rate are accommodated.
